Objective To explore the relationship between transitional care model and diabetic patients. Methods 112 patients with type 2 diabetes mellitus were divided into observation group and control group according to random number table. Control group used the doctor as the center patient management mode. The observation group used thepatient-centeredpatient management, application of home nursing service. Results Glycosylated hemoglobin (HbA1c), triglyceride (TG), high-density lipoprotein (HGL), 2 h postprandial blood glucose (2hPBG), fasting blood glucose (FBG), body mass index (BMI) of observation group before treatment respectively were (11.2±2.4)%, (3.7±1.3) mmol/L, (0.5±0.2) mmol/L, (13.6±2.4) mmol/L, (11.8±2.9) mmol/L, (25.9±4.9) kg/m2. Patients discharged from hospital after care for 3 months respectively were (6.8±0.9)%, (1.0±0.3) mmol/L, (2.5±0.4) mmol/L, (8.9±1.5) mmol/L, (6.8 ± 2.0) mmol/L, (20.8 ± 5.8) kg/m2. There was statistically significant difference (t=3.5-6.6,P<0.05). Control group before treatment respectively were (11.9 ± 3.6) %, (3.8 ± 1.5) mmol/L, (0.6 ± 0.3) mmol/L, (13.9 ± 2.9) mmol/L, (11.6 ± 3.2) mmol/L, (25.9 ± 6.8) kg/m2,while patients discharged from hospital for 3 months respectively were (10.9±3.4)%, (3.3±0.7) mmol/L, (0.7±0.2) mmol/L, (12.8±4.2) mmol/L, (10.6± 2.6) mmol/L, (25.1 ± 6.6) kg/m2, there was no statistically significant difference (t=0.05-1.36,P>0.05). Patients discharged from hospital after 3 months, perception, diet, medication, exercise adherence score of observation group was (34.98 ± 5.67), (41.98 ± 5.00), (40.29 ± 5.60), (40.45 ± 7.21) points, which were obviously higher than (21.18±4.75) , (28.46±4.26), (21.88±4.58), (20.98±2.69) points of control group, the difference was statistically significant (t=13.96-19.03,P<0.01). Conclusions Using home nursing service mode in type 2 diabetes care is helping to improve blood sugar levels and improve patient compliance after discharge, fully improve the patients′prognosis.

Background and purpose:Human epidermal growth factor receptor-2 (HER-2), a member of epidermal growth factor receptor family, initiates a diverse set of signaling pathways that ultimately affect such fun-damental processes as cell proliferation, cell motility and cell apoptosis. It is reported that HER-2 was associated with epithelial-mesenchymal transition (EMT) process. However, the mechanism needs further investigation. The purpose of this study was to investigate the mechanism of HER-2 on regulating EMT process.Methods:Transwell assay was used to determine the motility of breast cancer cells; Real-time lfuorescence quantitative polymerase chain reaction (RT-FQ-PCR) was employed to determine the expression of genes of interest, and reactive oxygen species production was measured by reactive oxygen species detection kit.Results:HER-2 overexpression in breast cancer cells could promote cell migration and invasion. Mechanistic study showed that HER-2 overexpression could upregulate ZEB1 expression. ZEB1 silencing by siRNA reduced cell motility of HER-2-overexpressing breast cancer cells. Furthermore, reactive oxygen species produced in HER-2-overexpressing breast cancer cells were less than those produced in corresponding control cells.Conclusion:Our study demonstrated that HER-2 overexpression endowed breast cancer cells with EMT related properties by upregulating ZEB1 expression. ZEB1 could be a candidate target for further study of the relation-ship between HER-2 and EMT.

Objective To investigate the effects of remote ischemic postconditioning (RIPoC) on global cerebral ischemia-reperfusion (I/R) injury in rats.Methods One hundred and twenty-eight male adult SD rats weighing 200-250 g were randomly divided into 4 groups ( n =32 each):sham operation group (group S),group I/R,group I/R + RIPoC and remote I/R group (group RI/R ).Global cerebral I/R was induced by four-vessel occlusion.Group I/R + RIPoC received 3 cycles of 15 min reperfusion followed by 15 min ischemia in bilateral femoral arteries at the beginning of cerebral reperfusion.The rats were sacrificed at 24 and 48 h of cerebral reperfusion,and brains were removed for determination of neuronal apoptosis (by TUNEL method) in hippocampal CA1 region and the parietal cortex,Bcl-2 and Bax expression (by Western blot) in hippocampal CA1 region.The superoxide dismutase (SOD) and catalase (CAT) activity and malondialdehyde (MDA) content in hippocampal CA1 region and the parietal cortex were also measured at 48 h of cerebral reperfusion.Morris water maze task was used to test the learning and memory function at 4 d of cerebral reperfusion,and the rats were sacrificed at 7 d of cerebral reperfusion,and brains were removed for determination of neuronal density in hippocampal CAl region and the parietal cortex.Results Cerebral I/R significantly increased the number of apoptotic neurons and MDA content,upregulated Bcl-2 and Bax expression,decreased neuronal density,SOD and CAT activity and learning and memory function in group I/R as compared with group S.RIPoC significantly attenuated these cerebral I/R-induced changes.Conclusion RIPoC could protect brain against global cerebral I/R-induced injury,and the mechanism may be related to inhibiting lipid peroxidation,regulating the balance between Bcl-2 and Bax and inhibiting apoptosis.

Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.
